Exception reading device databasehttps://www.microchip.com/forums/(c) Microchip30Re: Exception reading device database (d.)I talked with Microchip support on a related issue and mentioned this problem.&nbsp; They are aware there is a problem with EZBL with MPLAB-X v5.05, but don't know exactly what the problem is yet.&nbsp; I'll assume that they understand the issue and will come up with a solution.<br/>&nbsp;<br/>In the meantime, I've verified that there is no problem with a v4.05 project, and converting that to a v5.05 project creates the problem.&nbsp; I can work in v4.05 for the short term, but I will need to move on to v5.05 before implementing EZBL on my project.<br/>&nbsp;<br/>Dave<br/>https://www.microchip.com/forums/FindPost/1070223Wed, 03 Oct 2018 15:46:21 GMTRe: Exception reading device database (d.)Hi George,<br/>&nbsp;<br/>Thanks for the reply.&nbsp; First in response to your question, I've copied the project from one folder to another, changing the folder name (X project name).&nbsp; I've done this before and never had a problem.&nbsp; The correct device goes along with the project (PIC24FJ1024GB610).<br/>&nbsp;<br/>But I did find that the error is generated from within the makefile.&nbsp; This is a (as yet unmodified) EZBL bootloader project and the error is in makefile.uart.mk.&nbsp; This .mk file is automatically generated, but I haven't found from where.&nbsp; I can delete it, and it is re-created but compiles with the same error:<br/>&nbsp;<br/>EZBL: Editing MakeFile-uart.mk to enable EZBL Bootloader generation<br>"C:\Program Files (x86)\Microchip\MPLABX\v5.05\sys\java\jre1.8.0_144/bin/"java -jar "ezbl_integration/ezbl_tools.jar" --make_editor -conf=uart -min_free_psv=-1 -warn_free_psv=8192 -mcpu=24FJ1024GB610 -linkscript=,--script="ezbl_integration\ezbl_build_standalone.gld" -compiler_folder="C:\Program Files (x86)\Microchip\xc16\v1.34\bin" -java="C:\Program Files (x86)\Microchip\MPLABX\v5.05\sys\java\jre1.8.0_144/bin/" -project_name="Strip14Boot" -path_to_ide_bin="C:/Program Files (x86)/Microchip/MPLABX/v5.05/mplab_platform/platform/../mplab_ide/modules/../../bin/" -artifact="dist/uart/production/Strip14Boot.production.hex"<br>Exception reading device database: null<br>com.microchip.crownking.Anomaly<br> at com.microchip.crownking.edc.PIC.&lt;init&gt;(PIC.java:138)<br> at com.microchip.crownking.edc.PICFactory.create(PICFactory.java:152)<br> at com.microchip.crownking.edc.PICFactory.get(PICFactory.java:126)<br> at com.microchip.crownking.edc.PICFactory.get(PICFactory.java:138)<br> at com.microchip.apps.ezbl.CommandAndBuildState.ReadArgs(CommandAndBuildState.java:558)<br> at com.microchip.apps.ezbl.MakeEditor.main(MakeEditor.java:86)<br> at com.microchip.apps.ezbl.Main.main(Main.java:113)<br/>&nbsp;<br/>So it doesn't appear to be an MPLAB-X issue.&nbsp; Maybe I should create an EZBL ticket?<br/>&nbsp;<br/>Thanks for the reply.<br/>&nbsp;<br/>Dave<br/>https://www.microchip.com/forums/FindPost/1069875Mon, 01 Oct 2018 10:59:06 GMTRe: Exception reading device database (GeorgePauley)MPLAB X had an issue attempting to read the device data file.&nbsp; What device are you using?<br/>https://www.microchip.com/forums/FindPost/1069873Mon, 01 Oct 2018 10:43:50 GMTException reading device database (d.)Anyone know what this means?<br/>&nbsp;<br/>I copied a working v4.05 project to a new folder, then opened the new project in v5.05.&nbsp; The conversion took place.&nbsp; Doing a clean build in v5.05 I get:<br/>&nbsp;<br/>Exception reading device database: null<br>com.microchip.crownking.Anomaly<br> at com.microchip.crownking.edc.PIC.&lt;init&gt;(PIC.java:138)<br> at com.microchip.crownking.edc.PICFactory.create(PICFactory.java:152)<br> at com.microchip.crownking.edc.PICFactory.get(PICFactory.java:126)<br> at com.microchip.crownking.edc.PICFactory.get(PICFactory.java:138)<br> at com.microchip.apps.ezbl.CommandAndBuildState.ReadArgs(CommandAndBuildState.java:558)<br> at com.microchip.apps.ezbl.MakeEditor.main(MakeEditor.java:86)<br> at com.microchip.apps.ezbl.Main.main(Main.java:113)<br/>&nbsp;<br/>It then compiles all the files, and repeats the errors above.<br/>&nbsp;<br/>Ideas?<br/>&nbsp;<br/>Thanks,<br/>&nbsp;<br/>Dave<br/>https://www.microchip.com/forums/FindPost/1069607Fri, 28 Sep 2018 11:41:42 GMT
